Abstract
The invention discloses an ionomer-metal composite artificial muscle and a preparation method of the ionomer-metal composite artificial muscle. The method comprises the following steps of: polishing and ultrasonically cleaning a Nafion membrane, soaking in a NaOH solution to replace hydrogen ions in the Nafion membrane by sodium ions, soaking the Nafion membrane in a silver-ammonia soluotin to replace sodium ions by silver-ammonia ions, adding a reducer solution to the reaction system, allowing reaction to take place until no silver-ammonia ion is detected by NaNH4 aqueous solution test, and repeating the previous steps to allow attachment of silver to both the inside and the surface layer of the Nafion membrane. The method adopts silver as electrode which is easy to be reduced and has a relatively-low price, to overcome the problem that the application of gold, platinum or other noble metals as electrode has a high cost. Sodium borohydride with strong reducing property is replaced by glucose and vitamin C with moderate reducing property, so as to effectively control the speed of chemical reduction and reduce environmental pollution.
Description
Technical field
The present invention relates to belong to novel artificial muscle Drive technology field, more particularly, be specifically related to preparing method's metal composite artificial-muscle of a kind of ion polymer-metal combined artificial muscle and preparation method thereof.
Background technology
Artificial-muscle is a kind of type material with driveability.Common artificial-muscle is divided into Pneumatic artificial muscle and electronic artificial-muscle.Because Pneumatic artificial muscle need connect huge load when work, so be restricted in the application in miniature actuating field.Electronic artificial-muscle is divided into electron type artificial-muscle and ionic artificial-muscle again.The driving voltage that the electron type artificial-muscle needs is higher, and energy expenditure is big, and the ionic artificial-muscle can produce bigger actuation effect under lower voltage.
The ionic artificial-muscle by the ionic polymer matrix be positioned at matrix up and down the metal electrode on top layer be composited.Ionic polymer inside has been full of the hydrated cation that can move freely.When between upper/lower electrode, applying voltage of alternating current, hydrated cation can move to negative electrode, and the material of cathode zone is expanded, and anode shrinks owing to water molecules reduces, and artificial-muscle can produce the swing behavior like this, and electric energy is converted into mechanical energy.Because ion polymer-metal combined artificial muscle has that driving voltage is low, energy density is high, performance near Mammals muscle, quality is light and easy processing such as cuts at plurality of advantages, so have broad application prospects in mini drive, transmitter and artificial muscle field.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; A kind of ion polymer-metal combined artificial muscle is provided; Use is easy to reduce and the silver of relative low price is done electrode and overcome and use gold, platinum etc. to hold high the expensive shortcoming that high precious metals are done electrode; Selection has the glucose of gentle reductibility and the Peng Qinghuana that the vitamins C replacement has strong reducing property, effectively controls chemical reduction speed, reduces environmental pollution.
The object of the invention is achieved through following technical proposals:
The first, to the Nafion film polish with ultrasonic cleaning after, and be soaked in the NaOH solution, realize the hydrogen ion in the Nafion film is exchanged into sodium ion
The second, the Nafion film after the exchange is soaked in the silver ammino solution, to realize of the exchange of silver-colored ammonium ion sodium ion
The 3rd, in reaction system, add reductant solution and react, up to using NaBH
4Aqueous solution check is less than till the silver-colored ammonium ion, and elevated temperature is to 55-70 ℃ again, and the continuation reaction is taken out the Nafion film and cleaned after 1-2 hour
The 4th, repeat above-mentioned second and third step, so that the Nafion film is not only in inside, and also adhere to silver on the top layer
Wherein, described reductant solution is the aqueous solution or the vitamin C water solution of glucose, and the concentration of reductant solution is 0.07-0.075mol/L.
The concentration of described silver ammino solution is 0.030-0.035mol/L, and soaking temperature is 20-25 ℃.
Ion polymer-metal combined artificial muscle provided by the present invention is matrix with the commercial film of Nafion, and relatively inexpensive silver is electrode, has reduced the cost of making effectively.Through using gentle reductive agent: glucose and vitamins C, reduced the speed of chemical reduction reaction significantly, make electrode in the adhering to more firmly of matrix surface, all even densifications, the electroconductibility of electrode is also better.This ion polymer-metal combined artificial muscle has broad application prospects and higher utility in fields such as microrobot driving mechanism, microsensor and artificial muscles.
